Plunger pressing device for molding ingot

Abstract

Disclosed is an apparatus for pressing a plunger to form an ingot. The apparatus includes a base block having a tilted surface, a pair of guide rails disposed on left and right sides of the tilted surface of the base block, a support disposed on bottom ends of the guide rails and on which a molding frame is mounted, a sliding block which slides along the pair of guide rails and presses a plunger protruding upward from the molding frame, a pair of rotational frames coupled to be rotatable on hinges mounted below the pair of guide rails, and a pair of connection links having both longitudinal sides connected to the support and the rotational frames in a rotatable structure to move the sliding block downward when the rotational frames rotates downward.

What is claimed is: 
     
       1. An apparatus for pressing a plunger to form an ingot, comprising:
 a base block ( 100 ) having a tilted surface ( 110 ); 
 a pair of guide rails ( 200 ) disposed on left and right sides of the tilted surface ( 110 ) of the base block ( 100 ); 
 a support ( 300 ) disposed at a right angle with the tilted surface ( 110 ) on bottom ends of the guide rails ( 200 ) and on which a molding frame ( 10 ) is mounted; 
 a sliding block ( 400 ) which slides along the pair of guide rails ( 200 ) and presses a plunger ( 20 ) protruding upward from the molding frame ( 10 ), comprised a pair of sliding plates ( 410 ) mounted on inner surfaces of the pair of guide rails ( 200 ) and a pressing plate ( 420 ) disposed to be parallel to the top surface of the support ( 300 ) to connect the pair of side plates ( 410 ); 
 a pair of rotational frames ( 500 ) coupled to be rotatable on hinges mounted below the pair of guide rails ( 200 ) and connected a handle ( 700 ) on top ends of the pair of rotational frames ( 500 ); and 
 a pair of connection links ( 600 ) having both longitudinal sides connected to the sliding block ( 400 ) and the rotational frames ( 500 ) in a rotatable structure to move the sliding block ( 400 ) downward when the rotational frames ( 500 ) rotate downward. 
 
     
     
       2. The apparatus of  claim 1 , wherein the rotational frames ( 500 ) comprise hinge fastening holes ( 510 ) coupled to the guide rails ( 200 ) in a rotatable structure and link fastening holes ( 520 ) coupled to the connection links ( 600 ) in a rotatable structure, and
 wherein a distance between the hinge fastening holes ( 510 ) and the handle ( 700 ) is two times or greater than a distance between the hinge fastening holes ( 510 ) and the link fastening holes ( 520 ). 
 
     
     
       3. The apparatus of  claim 1 , wherein the connection links ( 600 ) comprise frame fastening holes ( 610 ) coupled to the rotational frames ( 500 ) in a rotatable structure and block fastening holes ( 620 ) coupled to the sliding block ( 400 ) in a rotatable structure, and
 wherein two or more of the frame fastening holes ( 610 ) and two or more of the block fastening holes ( 620 ) are arranged along a longitudinal direction of the connection links ( 600 ).
